In a specific embodiment, the self-contained power plant can participate in power grid interaction through the management of self-generated power resources, and becomes a new power main body in the power market. A single model of a traditional producer or consumer cannot correctly describe the economic characteristics and behavior of a self-contained power plant. Here, utility function models of the self-contained power plant enterprises are applied for analyzing the autonomous self-contained economic behavior.
(1) Self-prepared power station power utilization side utility model
The decision-making behavior of market users is often influenced by more abstract subjective willingness. To facilitate quantitative analysis, utility functions are introduced to describe the revenue value from the customer side of the power plant, i.e., power consumption. Self-contained power plants are generally considered to make decisions about their power consumption needs based on different scenarios. A utility function of power consumption in a product market is modeled as power usage per unit time as a revenue reference. It is understood that the power consumption of the self-contained power plant in the time period brings about an increase in economic satisfaction and increases with the increase in the amount of power consumption. J user side utility function U of self-contained power plantj(Pj) The following formula is given.
Uj(Pj)＝F(Pj) (6-1)
In the formula, PjThe power consumption of the user side j; when the user is not using electricity, the utility function is zero.
Suppose that the electricity purchase price of the user side j is lambdajThe electricity purchasing power is PbjThen, the utility function model at the user side of the self-contained power plant can be expressed as the following formula.
Uj(Pj)＝λjPb (6-2)
In the formula, P needs to be satisfiedb＞PjNamely, the electricity purchasing power is only a part of the electricity using power, and the self-contained power plant also has the self-generating capacity.
(2) Self-contained power plant power generation side cost model
The self-contained power plant generation side cost function represents the cost of providing energy, and is equivalent to the cost of generating electricity in an economically efficient manner by the generator i, and is usually a convex function. The power generation cost function C of the self-contained power plant can be represented by a quadratic functioni(Pi)。
In the formula, alphai> 0 and betai，γiAnd more than or equal to 0, representing each power generation cost coefficient.
When the electricity selling price of the generator i is larger than the electricity generating cost, the electricity generating side can obtain the profit by the electricity selling price lambdaiSell out PsAnd then the self-prepared power plant generates the self-power PSGThe cost-benefit of generating electricity when can be expressed as:
Ci(PSG)-λiPs (6-4)
(3) enterprise utility function
Considering utility function of user side of self-contained power plant, and considering spontaneous power PSGCost, electricity purchasing cost and electricity selling income can be obtained, an enterprise utility function optimization model is obtained, and constraint conditions are considered.
s.t.PSG≤Pmax
Pj≤Pjmax
Pb+PSG＝Pj+Ps (6-6)
In the formula, PmaxLimiting the power upper limit of the power generation side of the self-contained power plant; pjFor production power constraints; the constraint condition of the power balance of the self-contained power plant is as shown in the formula (6-6).
Renewable energy quota system and power generation right trade are considered. Considering the price cost lambda of the renewable energy quota system to be borne by the electricity producer and consumerres(ii) a The revenue for trading power generation rights involved in renewable energy consumption includes 2 components, namely, renewable energy subsidy transfer revenue λ'resAnd the cost is saved under the control of renewable energy quota. The utility function optimization model of the self-contained power plant is shown as the formula (6-7). The constraint conditions are as in formulas (6-8).
s.t.Pj≤Pjmax
Pres≤Pb
Pres≤Pres max
Pb＝PSG＝Pj+Ps (6-8)
In the formula, a constraint condition P of the power generation right transaction of the self-contained power plant enterprise participating in the consumption of the renewable energy source is newly addedresTo participate in the power generation right trading volume; pres maxTrading limits for power generation rights.
In principle, the basic conditions for the participation of self-contained power plants in the market are: benefit after participating in power grid interaction is more than or equal to total spontaneous self-service income Uj(Pj)-λresPj-Ci(Pj) That is, the expression (6-9) holds.
Ci(Pj)-Ci(PSG)-λjPb+λiPs+(λres+λ′res)Pres≥0 (6-9)
By combining the production utility function with the cost function of the producer, the self-contained power plant has been approximated as a "power consumer + generator" hybrid model with an independent objective function. Based on the generalized analysis method, the economic characteristics of various self-contained power plant enterprises and the participating markets of the self-contained power plant enterprises can be better analyzed in the follow-up process. The self-contained power plant enterprise is used as a utility function expression of the power generation and utilization of the individual self-contained power plant enterprise, and the utility function expression can be expanded to a power trading scene of a plurality of power generation and utilization through market interconnection for analyzing the response of polymorphic power generation and utilization participating in a power market.
The power generation cost of the self-contained power plant mainly comprises the following steps: actual costs (investment, fuel, labor, etc.) and enterprise profits + taxes (including additions, etc.), the simple computational model of which is: (annual power generation equipment depreciation amount + equipment maintenance cost + fuel cost + labor cost) ((1 + profit margin) ((1 + value-added tax rate)/annual power generation amount + government fund addition. The age-reduction amount AC is I × I × (1+ I) N/[ (1+ I) N-1 ], wherein I is the initial investment; i is the discount rate; and N is depreciation age.
The power generation cost of typical coal-fired self-contained power plants of each province (autonomous region) in the national network business region is quantitatively analyzed. The self-contained power plant has large power generation cost difference, is greatly influenced by factors such as areas (east, middle and west), unit types (coal straight condensing, coal-fired cogeneration, comprehensive resource utilization and the like), fuel types (coal, natural gas and the like) and the like, and is less influenced by factors such as service life, plant power consumption and the like.
In coal-fired self-contained power plants, fuel costs typically account for 60% -80% of the cost of electricity generation. For example, a typical coal fired cogeneration plant below 10 ten thousand watts north of foil costs about 0.41 yuan/kwh of electricity generation, with a fuel cost of about 0.33 yuan/kwh. And the power generation cost of a typical coal-fired cogeneration power plant of less than 10 ten thousand watts in Ningxia is about 0.51 yuan/kwh, with the fuel cost of about 0.36 yuan/kwh.
Fuel costs are generally higher in the middle east and lower in the west. The fuel cost of coal-fired self-contained power plants in coastal areas such as Hebei, Shandong, Jiangsu, Zhejiang and the like is usually 0.24-0.28 yuan/kilowatt hour. The fuel cost of coal-fired self-contained power plants in central areas such as Hubei and Hunan where coal input is difficult is usually 0.3-0.35 Yuan/kilowatt-hour. And the fuel cost of coal-fired self-contained power plants in western regions such as Shaanxi, Qinghai and Xinjiang is usually 0.1-0.2 yuan/kilowatt-hour.
The practically acceptable alternative to household prices are generally between the cost of electricity generated by self-contained power plants and the cost of fuel, typically 0.02-0.05 yuan/kwh lower than the cost of electricity generated. For example, a typical coal fired cogeneration plant, below 10 million watts in Shandong, costs about 0.5088 yuan/kwh of electricity, and a practical acceptable alternative is to a household price of about 0.47 yuan/kwh. The power generation cost of a typical Sichuan coal-fired straight condensing power plant is about 0.4 yuan/kilowatt hour, and the practically acceptable substitution cost is about 0.38 yuan/kilowatt hour.
The unit power generation cost is reduced along with the increase of the single unit capacity. Taking Jiangsu as an example, the cost of a large-scale public generator set is estimated according to a simple model, and the calculated non-tax fixed cost is 0.11-0.12 yuan/kilowatt hour and is close to the fixed cost data 0.10-0.13 yuan/kilowatt hour given by an investigation power plant. Therefore, according to the data of the coal consumption and the plant power rate of the power generation of the public power plant, the data of the power generation cost of a typical unit is obtained by calculating according to the 670 yuan/ton standard coal price, and the data are shown in the following tables 6-1 and 6-2. Simulating the typical power generation cost of a public unit for the supercritical unit above 600MW which is possibly participated in replacement, wherein the power supply cost with tax is 0.221 yuan/kilowatt hour, and the power supply cost without tax is 0.199 yuan/kilowatt hour.
TABLE 6-1 Power Generation cost data sheet for typical units in Jiangsu province (including tax, standard coal price 670 yuan/ton)
TABLE 6-2 cost analysis of typical self-contained power plants in Jiangsu
The coal-fired cogeneration unit comprises a condensation heat supply unit and a back pressure heat supply unit (comprising a back extraction heat supply unit), and the thermoelectric ratio of the units is greatly different. Analyzing the reported power generation coal consumption data, wherein the power generation coal consumption of some units is more than 350 g/kW.h and maximally exceeds 400 g/kW.h, which shows that the heat-power ratios of the units are not very high and the heat supply amount is relatively small; the power generation coal consumption of some units is very low, much of the power generation coal consumption is below 250 g/kW.h, the lowest power generation coal consumption is 135 g/kW.h, which indicates that the thermoelectric ratio is very high, the low power generation coal consumption indicates that steam generated by a boiler mainly supplies heat, and the power generation accounts for very low energy utilization ratio, and is close to a coal-fired heat supply boiler.

Model analysis is adopted for a coal-fired self-contained power plant with the power of less than 10 ten thousand kW, and the data adopted when the power generation cost is calculated relate to the data of an electric part in consideration of simultaneous power supply and heat supply of a cogeneration unit. The comprehensive production cost of the self-contained power plant is analyzed under the condition of considering the heat supply factor because the heat supply factor has great influence on the operation economy of the power plant; (2) the coal-fired self-service power plant calculation examples of 13.5 ten thousand kW and 30 ten thousand kW are taken into consideration of power supply cost and comprehensive cost. The following table shows the comparison between the electricity generation cost and the electricity selling cost of a certain cogeneration self-contained power plant enterprise. In this regard, little if any initiative for the self-contained power plant enterprise to participate in grid interaction exists without subsidy transfer of renewable energy.
TABLE 6-3 typical self-contained power plant and grid interaction cost analysis
TABLE 6-4 comparison of power generation and utilization costs of certain cogeneration self-contained power plant enterprises
(2) Trade economy evaluation under subsidy
According to the economic model of the proposed self-contained power plant as a producer and a consumer, obtaining the boundary conditions of the self-contained power plant participating in market trading: namely, after the power trading is participated, the profit of the self-contained power plant is not less than the profit which is not participated in the power trading, as shown in the formula (6-9).
To simplify the calculation, the following assumptions are made:
(1) the power generation cost function is a linear function, and the power generation cost is lambdaGS；
(2)Pb＝PresThe purchased electric quantity is all renewable energy sources to generate electricity;
(3)Ps0, not considering selling electricity;
the formula (6-9) can be simplified to the formula (6-10).
λSG(Pj-PSG)+(λres+λ′res-λj)Pres≥0 (6-10)
And is also provided with
Pj＝PSG＝Pb-Ps＝Pb＝Pres (6-11)
The two modes are combined and simplified
λSG+λres+λ′res-λj≥0 (6-12)
From the above formula, it can be seen that renewable energy transfers subsidizing electricity price lambda 'to ensure the initiative of the self-contained power plant to participate in market trading'resPositively correlated with the electricity purchase price, the self-generating cost and the price cost lambda of renewable energy quota systemresA negative correlation. Therefore, higher electricity prices in electricity selling markets and lower self-generating costs of self-contained power plants require higher renewable energy transfer subsidy electricity prices.
For example, the data of the self-provided power plant in Xinjiang in research are taken as the examples to purchase electricityElectricity price lambdaj0.33 yuan/kWh, renewable energy quota system price cost λres0.1 yuan/kWh. Tables 6-4 show the lowest renewable energy transfer subsidy prices required at different self-generating costs. It can be seen that when the cost of self-generation is low, high renewable energy transfer price needs to be subsidized; when the self-generating cost is high, even the price of electricity does not need to be subsidized, and the self-provided power plant can also automatically participate in the electric power market transaction.
TABLE 6-5 minimum renewable energy transfer subsidy price required at different self-generating costs
| λSG(Yuan/kWh) | 0.1 | 0.15 | 0.2 | 0.3 |
| λ′res(Yuan/kWh) | 0.13 | 0.08 | 0.03 | Does not need to use |
In addition, the transfer subsidy price of the renewable energy source is in a reasonable interval, the benefit of the self-contained power plant is not damaged, and the transfer subsidy price is within the bearing range of the new energy power plant, so that the multi-party participation in the power generation right trading market can be ensured, and the power generation right trading can be effectively operated. In fact, a special fund can be set by utilizing the income of the peak shaving market to share the subsidy price of the new energy power plant and inject more power for market trading.
The method and the device can promote and improve the electric power market mechanism of China. The method is characterized in that a self-contained power plant is guided to actively participate in electric power market transaction by a marketization means, and the electric power supply and demand regulation potential of the self-contained power plant serving as an electric power economy subject is fully adjusted; secondly, the structural improvement of the propulsion energy supply side. From the aspects of energy policy, supervision and management, market order and the like, scientific and standardized management of the self-contained power plant is realized, social responsibility and obligation are implemented, the self-contained power plant is promoted to become a qualified market main body, and the out-dated capacity is eliminated; and thirdly, clean energy consumption is promoted.
